Answer:
30 + 12y
Step-by-step explanation:
Width of the rectangle is given by (5+2y)
Length of the rectangle is twice its width.
= 2*(5+2y)
=10 + 4y
Perimeter of the rectangle is the sum of all four sides of the rectangle.
Hence perimeter is given by 2 * (length + width)
= [tex]\[2* [(5 + 2y) + (10 + 4y)]\][/tex]
Simplifying,
= [tex]\[2* [(15+6y)]\][/tex]
= [tex]\[(30+12y)\][/tex]
Hence the perimeter of the rectangle is given by (30 + 12y)
